Application tiled February 13, 1892. Serial No. 421,483. (No model.)

To a/ZZ whom it may concern).-

Be it known that l, FRANK C. W'ESTON, a citizen of the United States,residing at Bangor, in the county of Penobscot and State of Maine, haveinvented a new and useful Improvement in Bicycle-Lanterns, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification, inexplaining its nature.

The invention relates to a bicycle lantern, having the chimney supportedby a slide upon the side of a lantern frame, which preferably alsocarries a side light, and by the raising of which the chimney is liftedfrom the burner and an opening created through which the lamp may belighted and trimmed without opening the door, the chimney also beingsupported in all positions by the said slide.

Referring to the drawings: Figure 1 is a view in side elevation of thelantern without the attaching connection. Fig. 2 is a view in sideelevation thereof, the door of the lantern being open, the lamp beingpartially drawn out and the side slide carrying the chimney beinglifted. Fig. 3 is a view in front elevation of the lantern,the doorbeing open. Fig. 4 is a view in vertical section, to show the positionof the air chambers or channels. Fig. 5 is a view in detail, enlarged,representing especially the chimney support and connection with the sideslide.

The casing or frame A is preferably rectangular in shape. It has on oneside a slide B, which is vertically movable in suitable ways thereon,and which preferably carries the side light b. To the inner side of thisslide there is attached the chimney holder C by means of a horizontalarm c. The chimney holder is circular in shape and is of a size toreceive the lower circular section d of the chimney, the enlargement ofthe chimney above said section resting upon the upper edge of theholder. The slide, when closed, locates the chimney in proper relationto the burner, and when raised provides the opening b through which thelamp may be reached, lighted and trimmed; it being understood, ofcourse, that the lifting 0f the slide also lifts the chimney from theburner so that the wick is exposed.

The front of the lantern frame forms the door E, and it is hinged at onesid-e to the frame and is held at the other side in a closed position bythe latch c. It has, extending outward or forward, a case or shell e',which preferably is enlarged gradually, or flaring from its inner endoutwardly, and which is also in the main directed downward. lts end issomewhat inclined and is closed by the meniscus lens c2 (see Fig. 1),the lens being held inclined to a vertical line and so as to convergethe rays of the light upon the ground in front of the machine.

Upon each side of the frame, near the back, there is an air passage orchannelF (see Fig. 4). These channels or passages connect at their lowerends with the lamp chamber f and at their upper ends with a conicalchamber f', surrounding the upper part ofthe chimney and connected withthe lamp chamber f by the hole f2, through which the chimney extends,and with the chamber f 3, which surrounds the conical top and extendsfrom the chimney, connected with the outer air at j4 (see Fig. 4), thechamber f3 being formed by the hood f5 attached to the lantern frame.

There is in the side frame carrying the vertical slide a narrow apertureor recess h, extending from the front edge, which receives the spindleof the wick-raising device. This aperture is quite long and it is mainlycovered, when the slide B is closed, by a downwardly extending section hof the slide. (See Fig. l.)

A bicycle lantern having the features l have specified is very usefuland desirable, because l am enabled, by providing a suitable draft forproperly supporting combustion, to employ a chimney, and because, also,the chim ney is supported in a manner which largely neutralizes thedisadvantages coming from sudden shocks and blows.

Having thus fully described my invention, I claim and desire to secureby Letters Patent ofthe United States 1. In a bicycle lantern, thecombination with the lantern casing having a hinged front and a sideaperture, of a lamp in said casing, a vertically movable slide coveringsaid side aperture, and a chimney for said lamp supported from saidslide and vertically movable therewith, substantially as described.

2. In a bicycle lantern, the combination IOO With a lantern casingprovided With a side aperture, and an aperture for the passage of theWick controlling spindle of the burner, of a vertically movable'slideadapted to close both of said apertures, a lamp in said casing, and achimney for said lamp supported from said slide and vertically movabletherewith.

3. In a bicycle lantern, the combination with the lantern casingprovided with a hinged front and a side aperture, of a lamp in saidcasing, a vertically movable slide covering said aperture, a rigidsupporting arm extending from said slide to a central point Within thesaid lantern casing and a chimney mounted on said supporting arm andvertically movable With said arm `and slide to cover and uncover theburner, substantially as described.
